Background/purpose: This study investigated the effectiveness of Problem-Based Worksheets (PBWs) in improving conceptual understanding of logic gates. PBWs were designed with key characteristics that integrate authentic problem-solving, active student engagement, and conceptual scaffolding to support critical thinking processes. A total of 32…

Arguably, constructive alignment has been the major challenge for assessment in the context of problem-based learning (PBL). PBL focuses on promoting abilities such as clinical reasoning, team skills and metacognition. PBL also aims to foster self-directed learning and deep learning as opposed to rote learning. This has incentivized researchers in…

Educators have long lamented the tendency of students to engage in rote memorization in preparation for tests rather than engaging in deep learning where they attempt to gain meaning from their studies. Rote memorization driven by objective exams has been termed a steering effect. Progress testing (PT), in which a comprehensive examination…

Last year, 29 percent of New York City children were considered proficient in English and 35 percent in math on the state's challenging Common Core-aligned exams. For Success Academy students, the proficiency rates were 64 percent in English and an astonishing 94 percent in math. Success students in the city's poorest communities outperformed kids…

Vitellogenin (Vtg) is a lipid transfer protein that carries yolk to the ovary. The vitellogenin receptor (VtgR) mediates the uptake of Vtg into the oocyte of oviparous animals; its structure includes eight ligand-binding repeats (LBR). The binding site of VtgR and Vtg and the location of the interaction within the molecules are at these LBR.…

Students engaged in problem-based learning (PBL) units solve ill-structured problems in small groups, and then present arguments in support of their solution. However, middle school students often struggle developing evidence-based arguments (Krajcik et al., "J Learn Sci" 7:313-350, 1998). Using a mixed method design, the researchers examined the…

Unlike traditional lecture-based instruction, where information is passively transferred from instructor to student, problem-based learning (PBL) students are active participants in their own learning, thrust into unknown learning situations where the parameters of the problem may not be well-defined and the task at hand ambiguous--just like in…

In this laboratory experiment, high school students are challenged to prepare a six-layered chemical "rainbow" in a test tube. Students start with six unknown, colorless liquids and six pigments ranging from violet to red. The experiment is problem based and forces the students to apply their knowledge of solubility and density and combine it with…

Problem Based Learning (PBL) makes use of real-life scenarios to stimulate students' prior knowledge and to provide a meaningful context that is also related to the student's future professional work. In this article, Paternity testing is presented using a PBL approach that involves a combination of classroom, laboratory, and out-of-class…

A University of Hawaii study compared objective and subjective assessments of the three-step triple jump examination which tests medical students' clinical problem-solving processes. Subjects were 58 first-year students. Results found the subjective assessments were more consistent across problems of varying difficulty level than were objective…

Student performance in two different introductory biochemistry curricula are compared based on standardized testing of student content knowledge, problem-solving skills, and student opinions about the courses. One curriculum was used in four traditional, lecture-based classes (n = 381 students), whereas the second curriculum was used in two…

Examines various methods for assessing dental students' learning in a problem-based curriculum, including objective structured clinical examination; clinical proficiency testing; triple jump evaluation (identifying facts, developing hypotheses, establishing learning needs to further evaluate the problem, solving the learning needs, presenting…

The aim of the 2018 International Association for Development of the Information Society (IADIS) Cognition and Exploratory Learning in the Digital Age (CELDA) conference was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There have been advances in both cognitive…

This article discusses "Family Secrets," a problem-based learning (PBL) curriculum module that focuses on the bioethical implications of genetic testing. In high school biology classrooms throughout New York State, students are using "Family Secrets" to learn about DNA testing; Huntington's disease (HD); and the ethical, legal,…

A survey by the European Pharmaceutical Students' Committee of its member countries investigated the extent of problem-based learning, the effectiveness of examinations for testing knowledge, role of English as the language of instruction, best teaching methods, and relationships with other health occupations. Results and a position statement are…
